At my home country we used counter-weights, pulleys and cables. Took more space, it is arguably uglier (but who cares how it looks on the inside?) but the cable usually lasts for ages and fixing it is not a life-threatening procedure.
A torsion spring is great because as it unwinds, the tension decreases. As the garage door transitions from 200 lbs of vertical load in the closed position to almost 0 lbs when it's mostly parallel to the ceiling, a properly sized and wound spring reduces the force in synchrony with the door position.
Wouldn't a counterweight provide insufficient force at the bottom and/or excess force at the top?
But they require space and a sturdy housing. Springs are as compact as you can get.
There are also some safety concerns, a cable connecting the door to the counterweight can break, and/or slip. This can result in pieces of metal flying everywhere. A broken spring typically stays contained.
Personally, I would do one of the counterweight systems for my new house.
Not so for a 100%, 50%, and 0% open garage door. The 0% open door is the full weight; the 100% open door has very little weight (as most of the door is on the horizontal track).
Most of use would be just fine with a Toyota instead.
Actually I found out that now the more popular system for this kind of door there doesn't even use counterweights or springs, but an endless screw inside a rail or a linear gear.
